The Fuzzy Logic plus PID micropro-
cessor-based controller series, incor-
porate two bright, easy to read 4-digit
LED displays, indicating process va-
lue and set point value. The Fuzzy Lo-
gic technology enables a process to
reach a predetermined set point in the
shortest time, with the minimum of
overshoot during power-up or exter-
nal load disturbance.
C148 is a 1/16 DIN size panel mount
controller. The unit is powered by 90-
250 VAC or 11-26 VDC / VAC supply,
incorporating a 14V / 40mA output
for SSR as standard. There are six
types of alarm plus a dwell timer can
be configured for the alarm output.
The units are fully programmable
for PT100 and thermocouple types
„J, K, T, E, B, R, S, N, L“ with no need
to modify the unit. The input signal is
digitized by using a 18-bit A to D con-
verter. Its fast sampling rate allows the
unit to control fast processes.
By using proprietary Fuzzy modi-
fied PID technology, the control loop
will minimize the overshoot and un-
dershoot in a shortest time. The fol-
lowing diagram is a comparison of
results with and without Fuzzy tech-
nology.
CHAPTER 1 OVERVIEW 1-1 General

6User‘s Manual C 148 Temperature Controller
High Accuracy
The series are manufactured with
custom designed ASIC(Application
Specific Integrated Circuit) tech-
nology which contains a 18-bit A
to D converter for high resolution
measurement (true 0.1°F resolution
for thermocouple and PT100) The
ASIC technology provides improved
operating performance, low cost, en-
hanced reliability and higher density.
Fast Sampling Rate
The sampling rate of the input A to D
converter reaches 5 times / second.
The fast sampling rate allows this
series to control fast processes.
Fuzzy Control
The function of Fuzzy control is to
adjust PID parameters from time to
time in order to make manipulation
output value more flexible and adap-
tive to various processes. The results
is to enable a process to reach a pre-
determined set point in the shortest
time, with the minimum of overshoot
and undershoot during power-up or
external load disturbance.

CHAPTER 1 OVERVIEW 1-1 General
Auto-tune
The auto-tune function allows the user
to simplify initial setup for a new sys-
tem. A clever algorithm is provided to
obtain an optimal set of control para-
meters for the process, and it can be
applied either as the process is war-
ming up (cold start) or as the process
has been in steady state (warm start ).
Lockout Protection
According to actual security require-
ment, one of four lockout levels can
be selected to prevent the unit from
being changed abnormally.
Bumpless Transfer
Bumpless transfer allows the control-
ler to continue to control by using its
previous value as the sensor breaks.
Hence, the process can be well con-
trolled temporarily as if the sensor is
normal.
Soft-start Ramp
The ramping function is performed
during power up as well as any time
the set point is changed. It can be
ramping up or ramping down. The
process value will reach the set point
with a predetermined constant rate.
Digital Filter
A first order low pass filter with a pro-
grammable time constant is used to
improve the stability of process value.
This is particularly useful in certain
application where the process value is
too unstable to be read.
SEL Function
The units have the flexibility for user
to select those parameters which are
most significant to him and put these
parameters in the front of display se-
quence. There are at most 8 parame-
ters can be selected to allow the user
to build his own display sequence.

CHAPTER 2 INSTALLATION
Dangerous voltages capable of
causing death are sometimes present
in this instrument. Before installation or
beginning any cleaning or troubleshoo-
ting procedures the power to all equip-
ment must be switched off and isolated.
Units suspected of being faulty must be
disconnected and removed to a proper-
ly equipped workshop for testing and
repair. Component replacement and in-
ternal adjustments must be made by a
qualified maintenance person only.
This instrument is protected throug-
hout by Double Insulation . To
minimize the possibility of fire or shock
hazards, do not expose this instrument
to rain or excessive moisture.
Do not use this instrument in areas
under hazardous conditions such as
excessive shock, vibration, dirt, moistu-
re, corrosive gases or oil. The ambient
temperature of the areas should not
exceed the maximum rating specified in
Chapter 4.
Remove stains from this instrument
using a soft, dry cloth. Don‘t use harsh
chemicals, volatile solvent such as thin-
ner or strong detergents to clean the in-
strument in order to avoid deformation
or discoloration.
2-1 UNPACKING
Upon receipt of the shipment remove
the unit from the carton and inspect the
unit for shipping damage. If any damage
due to transit, report and claim with the
carrier. Write down the model number,
serial number, and date code for future
reference when corresponding with our
service center. The serial number (S/N)
and date code (D/C) are labeled on the
box and the housing of control.
2-2 MOUNTING
Make panel cutout to dimension shown
in Figure 2.1. Take both mounting
clamps away and insert the controller
into panel cutout. Install the mounting
clamps back. Gently tighten the screws
in the clamp till the controller front pa-
nels is fitted snugly in the cutout.

2-3 WIRING PRECAUTIONS
• Before wiring, verify the wiring label.
Switch off the power while checking.
• Care must be taken to ensure that ma-
ximum voltage rating specified on the
label are not exceeded.
• It is recommended that power of the-
se units to be protected by fuses or
circuit breakers rated at the minimum
value possible.
• All units should be installed inside a
suitably grounded metal enclosure to
prevent live parts being accessible
from human hands and metal tools.
• All wiring must conform to approp-
riate standards of good practice and
local codes and regulations. Wiring
must be suitable for voltage, current,
and temperature rating of the system.
• Beware not to over-tighten the terminal
screws. The torque should not exceed
1 N-m (8.9 Lb-in or 10.2KgF-cm).
• Unused control terminals should not
be used as jumper points as they may
be internally connected, causing da-
mage to the unit.
• Verify that the ratings of the output
devices and the inputs as specified in
Chapter 4 are not exceeded.
• Except the thermocouple wiring, all
wiring should use stranded copper
conductor with maximum gauge
18 AWG (0,75mm²).
